283 V8 or 292 I6?

Or fly past so fast they didn't see it. Just kidding, just kidding!

 

Go with the six and have a car that has some personality.

 

I think a lot of it depends on what rules from the past you're going to be using. Early G***er rules were very similar to later Modified Production cl*** rules. Heck, a modified 292 with automatic would be a nice bracket car today.
